.SH DESCRIPTION
.SS "/usr/bin/getconf, /usr/xpg4/bin/getconf, /usr/xpg6/bin/getconf"
.sp
.LP
In the first synopsis form, the \fBgetconf\fR utility writes to the standard
output the value of the variable specified by \fIsystem_var\fR, in accordance
with \fIspecification\fR if the \fB-v\fR option is used.
.sp
.LP
In the second synopsis form, \fBgetconf\fR writes to the standard output the
value of the variable specified by \fIpath_var\fR for the path specified by
\fIpathname\fR, in accordance with \fIspecification\fR if the \fB-v\fR option
is used.
.sp
.LP
In the third synopsis form, \fBconfig\fR writes to the standard output the
names of the current system configuration variables.
.sp
.LP
The value of each configuration variable is determined as if it were obtained
by calling the function from which it is defined to be available. The value
reflects conditions in the current operating environment.
.SS "ksh93"
.sp
.LP
The \fBgetconf\fR built-in in \fBksh93\fR is associated with the \fB/bin\fR and
\fB/usr/bin\fR paths. It is invoked when \fBgetconf\fR is executed without a
pathname prefix and the pathname search finds a \fB/bin/getconf\fR or
\fB/usr/bin/getconf\fR executable.
.sp
.LP
\fBgetconf\fR displays the system configuration value for \fIname\fR. If
\fIname\fR is a filesystem specific variable, the value is determined relative
to path, or, the current directory, if path is omitted. If \fIvalue\fR is
specified, \fBgetconf\fR attempts to change the process local value to
\fIvalue\fR. \fB-\fR can be used in place of path when it is not relevant. Only
writable variables can be set. \fBreadonly\fR variables cannot be changed.
.sp
.LP
The current value for \fIname\fR is written to the standard output. If
\fIname\fR is valid but undefined, \fBundefined\fR is written to the standard
output. If \fIname\fR is invalid or an error occurs in determining its value, a
diagnostic is written to standard error and \fBgetconf\fR exits with a
\fBnon-zero\fR exit status.
.sp
.LP
More than one variable can be set or queried by providing the \fIname path
value\fR 3-tuple for each variable, specifying \fB-\fR for value when querying.
.sp
.LP
If no operands are specified, all known variables are written in
\fIname\fR\fB=\fR\fIvalue\fR form to the standard output, one per line. Only
one of \fB--call\fR, \fB--name\fR or \fB--standard\fR can be specified.

.LP
See \fBlargefile\fR(7) for the description of the behavior of
\fB/usr/bin/getconf\fR when encountering files greater than or equal to 2 Gbyte
( 2^31 bytes).
.SH EXAMPLES
.LP
\fBExample 1 \fRWriting the Value of a Variable

\fBExample 2 \fRWriting the Value of a Variable for a Specific Directory

\fBExample 3 \fRDealing with Unspecified Results
.sp
.LP
This example shows how to deal more carefully with results that might be
unspecified:

.sp
.in +2
.nf
\fBif value=$(getconf PATH_MAX /usr); then
if [ "$value" = "undefined" ]; then
echo PATH_MAX in /usr is infinite.
else
echo PATH_MAX in /usr is $value.
fi
else
echo Error in getconf.

.LP
For example:

.sp
.in +2
.nf
\fBsysconf(_SC_POSIX_C_BIND);\fR
.fi
.in -2

.sp
.LP
and

.sp
.in +2
.nf
\fBsystem("getconf POSIX2_C_BIND");\fR
.fi
.in -2

.sp
.LP
in a C program could give different answers. The \fBsysconf\fR call supplies a
value that corresponds to the conditions when the program was either compiled
or executed, depending on the implementation. The \fBsystem\fR call to
\fBgetconf\fR always supplies a value corresponding to conditions when the
program is executed.

.SH ENVIRONMENT VARIABLES
.sp
.LP
See \fBenviron\fR(7) for descriptions of the following environment variables

\fBLC_CTYPE\fR, \fBLC_MESSAGES\fR, and \fBNLSPATH\fR.
.sp
.LP
The following environment variable is supported by the \fBksh93\fR built-in
\fBgetconf\fR command:
.sp
.ne 2
.na
\fB\fB_AST_FEATURES\fR\fR
.ad
.RS 17n
Local writable values that are different from the default are stored in the
\fB_AST_FEATURES\fR environment variable. The \fB_AST_FEATURES\fR value is a
space-separated list of \fIname path value\fR 3-tuples, where \fIname\fR is the
system configuration name, \fIpath\fR is the corresponding path, \fB-\fR if no
path is applicable, and \fIvalue\fR is the system configuration value.
